To all 'whom z't may concern.'

Be it known that I, DAVID 7.,

Flemington, in the county of'Hunterdon and State of New Jersey, haveinvented certain new and useful Improvements in Transmission Bands, ofwhich the following is a specification.

My invention 'relates to Ford transm1ssion bands. f l

My object. is to provide a deviceof this character which can be formedfrom old, or second-hand Ford parts, and therefore be made cheaperthanis possible to make devices intended for the same purpose, when soconstructed that they haveA to be made from new material.

Another object is to provide adevice of this character which,within-itself, Vis `of verycheap and easyA construction,- even thoughnew materials be used in making 1t.

Still another object is to provide a device in which the ear and bandwill have `prolonged and accentuated frictional engagement witheachother when the two are being disengaged, one from the other, butnevertheless so constructed that the initial disengaging Amovementiscomparatively easy. i f

VMinor objects will appear 1n the subjoined description. l Y L v-Theinvention consists in certain novel features of construction andarrangement of parts, as will'behereinafter described and claimed,reference being had to theaccompanying drawings, in which Fig. 1 is aperspective view showing the band and ear removably held in operativerelation to each other. v f

Fig. 2 is a vertical section showing the parts in the same position asillustrated in Fig. l; and,

Fig. 3 is a sectional view showing the parts in the position they occupywhile in the process of being disengaged from each other.

The numeral l indicates the brake band, 2 the brake lining carriedthereby, and 3 the ear.

The brake is rigidly secured to the under or concave face of the brakebandby means of the brass rivets 4 and 5 which have flat rounded heads4a and 5a respec-v tively. The brake band also carries three steelrivets 6, 7, and 8, located between the rivets 4 and 5, andapproximately equidistion with the-opening 9,.whenthe ear "and band-arebrought Ainto operativev relation to each other, so that when a reverse,movement of the ear'is attempted, they said .head ta .offers va .certaindegree of resistance thereto. .f *11j ff w It will also be noticed thatthe brass rivetA 5 is located only-slightly beyond .the `endofthe.ear,rso that `asisoon as.. the ear ismoved sufliciently 'toward the,left yon `the band ,1 to bring thelbottom of the ear up onto the headofthe rivet ,f'fthe tail end of the earbegins ,1 tantfromieachotheigwaiid theseisteel ,if ERNST, a` citizen of the United States,residing at to ride up vonthe head'- of the rivet, and.A

then the earV lheldupon the heads ofthe two .rivetsone ati' each end`rof the y.ear till 'the rivetsf, 7i, and 8,come into registration vwiththe openings' 9,10, and 11, which/iper.-

mits' the-.ear and bandtoibecome suddenlydisengaged.'y j `-`,Thisarrangement` f keeps the earand :band vfrom 4becoming loose on Ieachother .tilljthe parts: have ,reached f the. point where they i caniV beentirely rdisengagedz- But thefactthatlthe-earrides :up ont-the. head ofthelr'ivet'f before the-rivet'iis engaged, makes the initial disengagingmovement of the ear much easier.

The brake band 1 is provided at its section 12, which along with theshanks of the rivets 6, 7, and 8, serves as a stop for limiting themovement of the ear 'to the right. A screw driver can be insertedvbetween this ledge and the end of the ear for making theinitialmovement of the ear on vthe brake band, when it is desired todisyieldingly held for a prolonged period in binding engagement with thebrake band till the two are brought in position to be entirelydisengaged fromveach other. Thus for-`v i' Ward end with a littleupturned ledge or,y

it will be seen that the brass rivets 4 and 5 are made to serve two veryimportant purposes: first, to hold the brakes on the bands, andsecondly, to yieldingly hold the ear in vigorous and prolongedengagement with the band.

have provided a device of very simple, ef-y fective, and inexpensiveconstruction, which, with the exception ofthe rivets, can be easily andquickly made from second hand Ford parts.

The upturned end 12' at the forward endv of the band forms an abutmentwhich relieves the strain upon the rivets 6, 71, and 8, and causes thedevice to last longer.

Having now described my device, what I claim as new and desire toprotect by Letters Patent isr- 1. A. device of thev character described,comprising. a bandv and ear for removable engagement with each other;and a brake lining designed tobe carried by t-he band, the band having'brass rivets extending downwardly for engagement with the brake liningto hold the same rigidly on the band; and having upwardly extendingsteel rivets for sliding engagement with the ear to removably hold thesame on the opposite side of the band; said ear Ahaving openingsenlarged at one" end for the reception of the heads of the steel rivets,and having narrow portions extending rearwardly 'from said openings andadapted to receive the shanks of' said steel rivets; one of said'brassrivets l being arranged to register with the enlarged portion ofthe forward one of said enlarged openings in ther ear, with the head ofthe rivet projecting into said opening when the ear and band are intheir normal position relatively to each other; whereby to cause saidrivetvhead to form an obstruction to the movement of the ear on theband.

2. A device of the character described, comprising a band and ear forremovable engagement with each other; and a brake lining designed to becarried by the band,

the band having brass. rivets extending downwardly for engagement withthe brake lining to hold the same rigidly on the band; and havingupwardly extending steel rivets for sliding engagement with the ear.y toremovably hold the same on the opposite Vside of the band; said earhaving openings enlarged at one end for the reception of the heads ofthe steel rivets, and adapted to receive the Shanks of'said steelrivets; one of saidI brassv ri'vets being arranged to register with theenlarged portion of the forward one of said enlarged openings in th'eear, with the head of the rivet projecting into said opening when theear and band are in their normal position relatively to each other;whereby tov cause said'rivet head 'to form an obstruction to themovement of theear on the band; rthe other brass rivet being located innear'proximity tov the rear end of the ear to engage the same after itsinitial rearward movement; whereby when the front end of the yoke ri'desup on the first named rivet, the rear end of the ear begins riding up onthe rear rivet; to cause both rivets to be in engagementwith the ear,one at each end thereof, during all except the' initial part-of thedisengagingv movement of the ear on the band.
